The children’s museum has a large fish tank with the dimensions shown. the tank does not have a cover. what is the surface area of the fish tank.

The answer is 230 square feet.

Step-by-step explanation:

Find the area of the bases, and  the total of it is 280. I then subtracted 50 because the "covers" area is 50. That gives you the surface area without the cover

230 square feet

Step-by-step explanation:

The surface area is found by finding the area of each surface and adding them together.

The front and back faces have areas of 10(6) = 60 feet.  There are two, so this is 2(60) = 120 square feet.

The right and left faces have areas of 5(6) = 30 feet.  There are two, so this is 2(30) = 60 square feet.

The bottom face has an area of 10(5) = 50 feet.

This gives us a total area of 120+60+50 = 180+50 = 230 square feet.

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
